What You Need to Know
During steaming at ~100 °C, linamarin and lotaustralin hydrolyze to produce hydrogen cyanide, which volatilizes, while phenolic compounds from banana leaves such as eugenol and methyl‑cinnamate diffuse into the leaves, creating characteristic aroma. The process also reduces antinutrients and preserves some vitamin C.
The Science
Primary Reaction
Hydrolysis of cyanogenic glycosides (linamarin, lotaustralin) → hydrogen cyanide + sugars
